The Planes

Beyond the confines of the Universe lie the vast planes of existence referred to as the Great Beyond. Often alien and dangerous, most of these planes embody some foundational aspect of reality—one of the chief elements that make up the rest of the multiverse or a kind of fundamental energy. Each plane is a reality unto itself, with its own laws of existence and its own native inhabitants who might visit, grant benefits to residents of, or cause havoc on the Universe.
